What is shaft design?

What is shaft design?

Shaft is a common and important machine element. The shaft is generally acted upon by bending moment, torsion and axial force. Design of shaft primarily involves in determining stresses at critical point in the shaft that is arising due to aforementioned loading. Other two similar forms of a shaft are axle and spindle.

What are the 3 main design considerations in the design of shafts?

Shaft design considerations include:

• Size and spacing of components (as on a general assembly drawing), tolerances,
• Material selection, material treatments,
• Deflection and rigidity, a. Bending deflection, b. Torsional deflection, c.
• Stress and strength, a. Static strength, b. Fatigue, c.
• Frequency response,

How do you calculate shaft design?

Basic Shaft Design Formula

1. M is maximum bending moment on the shaft.
2. r is the radius of the shaft.
3. I is area moment of inertia of the shaft.
4. Input data:
5. Solution:
6. I = pi * r^4 *0.25.
7. = 0.785*r^4……………….. Eqn. 1.2.
8. r= 12.85 mm.

What should be the first properly during design of shaft?

What should be the first property of the shaft design? Explanation: The shaft design should be such that the shaft must have enough mechanical strength. The strength should be such that it should withstand all loads without causing much residual strain.

How many types of shafts are there?

Shafts are mainly classified into two types: Transmission shafts are used to transmit power between the source and the machine absorbing power. e.g., countershafts, line shafts, and all factory shafts. Machine shafts are an integral part of the machine itself.

What should be the first property of shaft design?

How many ASME codes are there?

ASME codes and standards It produces approximately 600 codes and standards covering many technical areas, such as fasteners, plumbing fixtures, elevators, pipelines, and power plant systems and components.

What is the shaft material?

Materials. The material used for ordinary shafts is mild steel. When high strength is required, an alloy steel such as nickel, nickel-chromium or chromium-vanadium steel is used. Shafts are generally formed by hot rolling and finished to size by cold drawing or turning and grinding.
